A fraction is written in terms of two parts: the number on top is called the numerator and the number on the bottom is called the denominator. We can use the division method to solve this question. To get a decimal, simply divide the numerator 139 by the denominator 27:
139 (numerator) ÷ 27 (denominator) = 5.15
As a result, you get 5.15 as your answer when you convert 4 31/27 (or 139/27) to a decimal.
